I shoot in Raw. Edit in LR/PS. then change over to JPEG and upload to say Shutterfly or another in kind service. I notice that the color and detail have been less than those that I have uploaded. Is there any way RAW or TIFF files can be uploaded? Do any online services provide for such formats?

The 9900 processes and prints 16 bit with the native driver, unless they have changed that since it was released:

And it can do it with a hardware or software RIP in any case. It is a wide gamut printer and leverages it's increased bit depth (in internal processing and output) to produce better images.

The above reference (and the other one, that I've snipped) both say that it will process 16-bit data. Technically what that says is that if you input a 16-bit TIFF file it won't choke. It says nothing about maintaining a 16-bit workflow right down to the hardware.

In fact at least part of the driver is almost certain to maintain the 16-bit depth. But the data sent to the physical printer is 8-bit.

Did I get it right?

You got it right.
Raw is your negative so protect it for future use as a tiff or jpeg as you desire.
I shoot in RAW with a low quality jpeg also created in camera so if someone wants a "picture" real fast it can be e-mailed easily as is. (Good enough for facebook or other locations for crappy photos of that type.)

Each manufacturer's raw format is different. I know of no online photo sites that support raw image display. And because TIFF files are so large, I also suspect that no online sites support their use either.

Some cameras such as the Nikon D800 have an option of recording the original image as a tiff file, with no post processing required.

If you have a camera that can shoot in TIFF, yes, but not all cameras do so. I've only ever had one that did. Neither TIFF nor RAW are compressed files that lose anything, and RAW is more flexible during conversion to another format, so I don't see the point.

What's the better file over JPEG, Raw or TIFF

As FredB said above. Apples vs Oranges. Plus TIF or tiff files are uncompressed though large they are universally viewable as are JPG or jpeg files. JPG files are like mp3 files, a lot of information is missing to make them small.

Raw are proprietary files that your camera creates. They are just that, exactly what the sensor saw, no processing but contain the most information. A few manufacturers like Pentax and Leica use Adobe DNG files as their Raw format. But like other Raw files you need Ps, Lr, PSE, and ACR to read them. But any version of ACR should work on any DNG file.

Personally I shoot in Raw (DNG) 14-bit, process in and save work in PSD 16-bit, and convert to jpg 8-bit for printing or Web publishing. And occasionally if passing them on to someone else or for high quality archiving, I'll save as TIF files.

This is an unclear statement. I think you have TIFF confused with raw. Raw files will ALWAYS remain "unchanged", as any changes to them are reflected only in the resultant non-raw output file, and edits to the raw file are kept in a separate file, sometimes called a sidecar. Whether you save an edited raw as TIFF or JPEG to reflect the changes makes no difference to the raw file itself.

It's easiest to simply think of the raw file as your undeveloped strip of film, just like in the old days. You run it through the developer and fixer and all that junk, and then you make a PRINT from it. The plastic strip of film that came out of your camera is not changed, per se. (Yeah, I know, in reality it is altered, but for my purposes of illustration, if you just think of raw as your strip of film, it's easier to visualize the difference between raw and JPEG or TIFF.

If you get a JPEG or TIFF straight out of your camera, it's like a Polaroid vs developed film.

No, I do not have Tiff confused with Raw. I understand that Raw is unchanged. I am talking about how to save the files.

Raw is not an image but lots of information, far more than a Jpeg file. After editing, if you save your file to Tiff, you retain all the steps you took in editing and can go back and make changes to those edits. If you edit a file and save it as a Jpeg, you lose all the steps you took in your editing process and can not tweak any of the previous edits.

Save to jpeg for the web or if you want a small file for emailing. Save to Tiff so that you can go back and make changes in the future. A Tiff file is considerably larger than a Jpeg file. Much too large to email in quantities.

The Jpeg file shows the editing that you have done, but you can not go back and tweak any of those steps. The Tiff file saves all your steps and you can tweak any of those steps after you have saved the file.

Sorry for all the confusion with my dumb question.
What I really meant to say if you shoot in raw and then edit the file to print later is it best to save in tiff or jpeg.


That's what I thought you meant and my replies addressed your restated question ;)

Exactly right.

TIFF is a 16-bit format, which means that it can represent a couple hundred TRILLION shades of color. JPEG is an 8-bit format, which, by comparison, can represent "only" 16 million and change. Now you might be saying, "Sheesh, FredB, what the heck difference can it make...? ", but it can make a BIG difference when PRINTING.

Your video monitor is a stone axe compared to the capabilities of a modern, decent ink-jet printer, especially a big ass mutha like they use at professional print shops, or even Costco.

Thus, if you're going to PRINT at anything larger than wallet size, a TIFF image is nearly always going to be 1) Preferred by the printer, and B) Better Quality in terms of Output.

A TIFF and a JPEG side-by-side on your computer monitor would not show much difference, as the display mechanisms are far less sophisticated than a good printer (unless you're looking at a $25,000 SONY control room monitor, which I doubt many of us are...)

When I edit I use 8 bit. No need for 16 bit. The human eye can not tell the difference. I always save to Tiff so that I can make changes to the editing later if I see the need to do so.

Not necessarily. Not all camera's do the capture in Tiff (Tagged Information File Format).

When I was shooting Olympus DSLR, the camera offered options of Jpg, RAW, and Tiff. I seem to recall my Fujifilm S2, S3 and S5 Pro model DLSR's offered Tiff as an option.

Check your camera, or the manual for the possibility to shoot Tiff. You may have to shoot RAW and then convert to Tiff in the computer, with your editing software.

Sorry, but the highlighted statement is not correct. When you edit a raw file, whether you save to TIFF or JPEG is immaterial. You are confusing the LOSSY (compressed) saves that happen to a JPEG file with the LOSSLESS (uncompressed) format of a TIFF file.

An edited raw file will always be re-editable, since the changes do not overwrite original data, but are saved as a sidecar or other mechanism.

UPDATE:
Ok, I've gone back over your original statement, my first reply, your response, and now my 2nd response. I am completely puzzled by your statement that TIFF files somehow retain all the editing actions that you make on them.

Are you saying that you can edit a raw file, make a bunch of changes to it, save the edited raw as a TIFF file, and then open the TIFF file and be able to UNDO the changes that were made while you were editing the raw file? That doesn't make any sense.

Or are you saying that you can open a TIFF file, make a bunch of changes, save it, then re-open it and undo those changes? Huh? I've never heard of this capability. I know all about the ability to UNDO in varying amounts, during a SINGLE session with various editors, but I've never heard of the ability to 'store' edits to a TIFF file and then re-open it, ostensibly days later, and UNDO those individual editing actions.

Now, it may be that your P/P program somehow saves actions done against a TIFF file, so that you can reopen that same file later and undo those actions, but that's a function of the P/P software, not a TIFF file generically.

I do not use Photoshop or any of its derivatives so perhaps that's where this confusion comes in?
